(4x+1)(x)=663
We move all terms to the left:
(4x+1)(x)-(663)=0
We multiply parentheses
4x^2+x-663=0
a = 4; b = 1; c = -663;
Δ = b2-4ac
Δ = 12-4·4·(-663)
Δ = 10609
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{10609}=103$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-103}{2*4}=\frac{-104}{8} =-13 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+103}{2*4}=\frac{102}{8} =12+3/4 $
